BAMS has better scope.

What are your scores in class boards and CET?
Hopefully, BDS is much better.

BAMS AYURVEDIC IS IN ACCEPTING THESE DAYS

Bhuvana,
Why do you want to go for management quota seat? They are expensive due to which many remain vacant and deserving students miss out on opportunity to get quality education.
Many good and big universities like LPU, Amity, SMU, etc. are there that offer admission to students on the basis of their own test as well as marks in 12th. They are the universities which offer world class environment to their students along with good placements. Some of these universities also offer good scholarships to students.
Check their websites or call their toll free no.s.
Good luck.

Although this is quite a rare choice, however you can opt for hospitality management as there are many resorts that are either rehabilitation or medical resorts where people from various medical condition come to be treated with help of ancient Ayurveda. Hence your knowledge of BAMS would be useful there.
